摘要：

A 100 ns excimer laser-produced copper plasma was used to investigate the Na-like Cu XIX n = 4-2 satellite emission in a higher density and lower temperature regime than previously studied. Theoretical model. calculations were used to identify a number of radiative transitions from autoionizing Na-like copper levels. These transitions were measured with an accuracy of 0.001 Angstrom. A comparison of these spectral measurements to spectra obtained from lower density Nd-glass laser-produced copper plsmas demonstrated the changing role of different excitation mechanisms for different plasma conditions.
